Application fil d November 10, 1919. Serial No. 39i6,864.

To all whom it may concern; Be it known that 1, DAVID JosnPH SMITri lieutenant-colonel, a subject of the Kingof Great Britain, and a resident of {0 Wood}- berry Grove, Finsbury Park, London, N. 4;, England, have invented new and useful Irriprovements in and Connected with Gas Prqducers, of which the following is the specification. a j j This invention relates to the means fer feeding the fuel to the producer and to oertainimprovements connected therewith,- and it, relates in particular to improvements the producer described inm prior specifications Serial No. ZMJLL entitled Improvements in and connected with gas producers, and No. 264,715, entitled Improvements in and connected with gas producers for propelling vehicles. M

The object of the invention is to provide better means for supplying the fuel to the producer from a hopper or other source of supply, and embodied therewith are rnea ns for readily displacing and replacing the feeding means when it is desired to inspect theproducer or when starting same. A

I provide preferably at the top of the producer a machined surface for a joint which surface is preferably of plane form, and arranged on one side of the producer, The flange which is adapted to fit the said surface forms the foot of and the secuning means for the supply or delivery tube from the hopper or like storage receptacle of the fuel placed above the producer. The upper portion of the said feed tube is vertical'or approximately vertical, and the lowerportion is disposed at an angle to the vertical, the lower portion being so mounted on securod to the upper part that it is adapted t? be readily turned bodily upon its or axis. Located just above the said flanged provide a cylindrical casing or housing haw ing fitted theiein a hollow cylindrical plug having a port therein, which during its rotation is presented to the feed pipe containing the nuts of coal or other fuel above it, and the plug thereupon becomes filled with the fuel. the rotation being continued, the port in the plug is presented to the opening to the producer and the contents are discharged either into the producer or alternatively to the screw feeder described in the said prior specifications. The rotation of the plug is effected by means of a ratchet wheel and lver,or other one-Way clutch Of known construction operated by one of the shafts as describdin the said specifications. The foot or base flange is provided with a pivot pin upon which the flange and the rotary plu feeder are bodily turned, a pivotal soc et connected to the said flange bein adapted to fit a recess in the casting or the like, at the top of the producer. I provide secured verticallyupon the same flange a length of pipingformed with a joint at its upper end in such manner that it may for a relatively gas tight fit with the lower 61:3 of a similar fixed pipe when theflange is swung over upon its pivot. This pipe constita rtesthe smoke pipe employed especially when starting or when the producer is ternporarily out of operation.

i The tvvo ends 0f the smoke pipe are so formed witlt an angular edge, or with semicircular opposed overlapping flanges that they make goodjoint when the two ends are brought into engagement. L

The upper length of the said pipe may be secured to ,erJaep-laced at the side of the said hopper on a vhiole. i

Thus when the curved flange carrying the fuel feeder and the said vertical pipe are turnedupon the pivot in,one direction, the

i'fuelwfeeder is removed laterally from the aperture at theto 0f the producer andthe said verticahor smoke pipe may be caused-to register therewith, but the fuel delivery or outlet is olosedby the curved extension of saicbfnced surface on the producer. When thecurved flange is turned in the other directioni-t giwes free access to the interior of the producers i i M the producer is mounted on a vehicle the happen 'iniay he formed; in or on the canopy or cover over the head of the driver.

I may .providein the upperportion of the fuel pipe just above the pivoting joint a slot which slot-or a part of same may be covered with glass. The said slot may be so positioned as to be within view of the driver of the vehicle A swing bolt is provided tolock the pivoted flange H1 position carrying the feeder and smoke pipe and to keep same gas tight.

The described arrangement permits of the inspection of the interior of the producer without the necessity as so frcqucntly has hithcrio occurred of the removal of the whole feeding apparatus from the top of the producer. This invention further -pl'qvides a convenient seal or closure when desired, or alternatively conveys the gas through the smoke pipe. ca1-e of a producer used for industrial purposes may he passed through the roof or This pipe in the,

Within the casing E and adapted to rotate therein is fIEed-the cylindrical plug E. The casing E also carries the bracket J which is provided at each end with bearings,

in which bearings the shaft K is mounted and adapted to rotate (see Fig. i). The

wall of the building, or in the case of ztfi shaft K is secured at the inner end to the C! the head of the driver.

In larger industrial producers, the said pivoted faced flange and apparatus carried thereon, may be operated by power.

The smoke pipe may be of suiiicient length to form a flue, and the draught of this flue can be used to keep the fire while the producer is not operating in a suitable condition tor starting, with the minimum of, or without blowing up by a fan. This would be accomplished by swinging the curved flange to one side and bringing the smoke pipe over the aperture in the producer and making a joint with the extension of the smoke pipe fixed to the hopper or canopy or building as previously described.

The accompanying drawing illustratesthe preferred mode of carrying the invention into effect.

Fig. l is an elevation showing a portion of the top of the producer with the apparatus according to this invention mounted thereon.

Fig. 2 is a plan of Fig. 1 with the hopper removed.

Fig. 3 is a plan showing the feed pipe removed from the producer aperture.

, Fig. i is a section of the feeding plug and its casing.

A represents in Figs. 1 and 4 a portion of the top of the easin of the producer, this is shown in plan, Tigs. 2 and B is the hopper or fuel container. C is the machined plane surface providing the sliding joint at the top of the producer. D is the flange or plate adapted to slide on the machined surface. E is the cylindrical casing provided in the feed pipe or channel F for fuel. The upper part or extension i of this feed pipe is titted into a socket F so that the lower portion F F is adapted to be turned or have a partial rotation upon the fixed portion F attached to the hopper B. This turning movement is effected upon the centre or pivot pin Gr fitting in the socket G The flange D is preferably formed integrally with the centre or pivot pin G and has mounted thereon or is integrally formed with the casing E, the length of pipe F, and the socket F On the same flange D is also mounted the short length of smoke pipe H. This portion of smoke pipe H is provided at its upper end with a cutaway or recessed part H which is adapted to engage and. closely tit With a similar rereresed or cutaway portion 1 upon the tired or upper part of the smoke pipe 1.

vehicle, throiwh said canopy or cover above rotatable cylindrical plug E and has secured at the other end the one-way clutch L fitted within the housing L The said one-way clutch may be of any suitable kind such as a frictional clutch of the free-wheel type, or it may be of the ratchet and pawl type. The one-way clutch L is operated by the lever arm M which is secured to and adapted to rock or oscillate u on the clutch L and shaft K. The arm M is operated by the connecting rod or lever N which may be reciproeated in the manner described in the said prior specification or in any other suitable manner by the power means employed for operating the producer. In the fixed fuel feed pipe F is provided a slot 0 having fitted therein a. piece of glass. It is arranged opposite the driver through which he may see the position or condition of the pile or column of fuel contained in the feed pipe F at any time, and by this means perceive whether the fuel is feeding freely or whether there is any tendency to jam in the pipe;

The cylindrical rotatable plug E is pro vided as shown in the section, Fig. 4, with a port P therein, which is adapted by the continuous rotation of the shaft K by means of the rocking arm M and one-way clutch L to be brought into register when the port is in its uppermost position, with the fuel feeding pipe F, and the small nuts of fuel therein consequently fall into the cylindrical plug through the port F and fill same. The continued rotation of the plug E brings it to its lowermost position at which the fuel contained in the plug is discharged or falls through the port P into the opening or orilit-ell at the top of the producer.

The shaft K is also provided at its outer end with a hand lever R in order that the plug may be operated by hand in starting the producer.

When it is desired to inspect the. interior of the producer through the opening or orifice Q, the flange D with the parts previously described mounted thereon or secured thereto, may be turned bodily upon the pivot pin G by releasing the rocking bolt and flynut which bolt is adapted to fit the slot S in the arm S The described apparatus and parts are then in the position shown in theplan, Fig. 3, in dotted lines marked T. This leaves the aperture Q open and clear for the inspection of the producer.

When the apparatus is in the position sliou n in the plan. Fig. the fuel i QPil pipe registers with the opening Q. in the prmlurer till) and fuel may be fed through this aperture or opening. This is also the position of the elevation, Fig. 1. hen the apparatus is in the position shown in full lines in Fig. 3, the feed pipe is turned upon the pin Gr out of the feeding position, and the overlapping section H of the lower part of the smoke pipe H is adapted to fit and closely engage with the corresponding cutaway portion 1 of the upper or fixed part of the smoke pipe I. The producer is then in such position adapted for starting the fire or for maintaining the producer furnace in a nonoperative or potential condition, sufficient r draught being created by the smoke pipe I forming a chimney to just maintain the combustion in the producer furnace.

What I do claim as my invention and dcsire to secure by Letters Patent is l. The combination with a producer provided with a fuel opening, of a fuel supply pipe pivotally mounted on the producer to swing in contact therewith and in and out of register with the fuel opening, whereby when said supply pipe is out of register with said opening, the opening will be uncovered to permit of inspection of the fire.

2. The combination with a producer hav ing an opening in its top, of a fuel supply pipe, a smoke pipe, and means for mounting said pipes so that either can be brought into register with the said opening.

3.-The combination with a producer having a common fuel and smoke opening, of a fuel pipe, a smoke pipe, and means for pivotally mounting the said pipes so that the pipes can be alternately brought into and out of register with the said opening.

i. A gas producer provided with an open ing, a plate, and a fuel feed pipe and a smoke pipe pivotally mounted on the plate by a pivot eccentric to the opening, so that either may be caused to register therewith.

5. A gas producer having a machined or plane. surface at the top and provided with a socket, a fuel feed pipe and smoke pipe, and a plate carrying the said pipes and having a pivot pin engaging the socket.

(3. In a gas producer fuel feeding means having an inclined pipe adapted to be pivoted on a part having a telescopic socket in its upper part adapted to fit a fixed feed pipe above it, which fixed feed pipe is concentric with the pivot.

7. A gas producer having an opening, a movably mounted fuel pipe, a movably mounted smoke pipe, and means whereby either pipe may be made to register with the opening of the producer or the opening left exposed for inspection of the interior of the producer.

8. A gas producer having an opening in its top, a pivotally mounted member carrying a feed pipe and a smoke pipe and adapted to be moved to cause either of the pipes to register with the opening in the casing, and a cylindrical plug mounted in the feed pipe and having a port therein adapted to alternately register with the fuel pipe and the opening of the casing.

9. In a gas producer, a casing having an opening in its top, a plate-like member pivotally mounted on the casing and carrying a feed pipe and a smoke pipe and adapted to be moved to cause either of said pipes to register with the opening of the casing, a rocking lever for locking said member in position, a cylindrical plug mounted in the feed pipe and provided With a port, and a rotatable shaft carrying the plug and fitted with a one-way clutch.

it). In gas producer having continuously operating fuel feeding means when the feed pipe registers with the opening of the producer, a lever at the end of the shaft specified in claim 9 to operate the feeding means at starting.
